To all whom it may concern:

Be it known that 1, JOHN JAMES ALLEN, a subject of the Queen of Great Britain, residing in Halifax, in the county of York, England, have invented certain new and useful Improvements in Machines for Guinming Paper, of which the following is a specification.

This invention constitutes the subject-matter of Letters Patent in Great Britain No. 1 3,383,dated November 5,1885, and in Austria- Hungary No. 21,137, dated May 13, 1886.

This invention relates to machines to be employed for applying a coating of gum or paste to paper or labels, thereby dispensing with the use of a brush and avoiding the waste and labor incidental to hand-gumming.

My improved machine is constructed with a gumming-roller revolving in a trough or vessel containing the paste or gum, with a strickle or scraper for removing the excess of gum from the roller, and with devices for feeding the paper or labels into contact with the gummed surface of the roller in order that it may impart its coating of gum to the paper or label.

The paper or label is fed by a feeding-roller,

and passes between the periphery of the gum ming-roller and a guidebar, by which it is held in contact with the gumming-roller. The gummed paper is lifted off from the gummingroller by a spur or finger over which it rides and which directs it out of the machine.

Figure 1 of the accompanying drawings is a plan view of the machine. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical transverse section cut through line A B in Fig. 1. Fig. 4 is an end View of the machine. Figs. 5 and 6 are elevations of the locking plates on opposite ends of the machine. Fig. 7 is a fragmentary end elevation looking in the same direction as Fig. 3. Fig. 8 is a front elevation of the feeding or intake roller and feed-plate. Fig. 9 is an end elevation of the gumming-roller guide-bar, intake-roller, and feed-plate; and Fig. 10 is a plan of the gumming-roller and strickle.

The several parts are designated by reference-numbers, of which Number 1 designates theintake roller or feed; 2 2, rubber rings placed thereon at intervals; 3, the gu1nming-roller; 9, the guide-bar; 10, the feedplate, and 12 the strickle.

The entire mechanism is mounted on a box or base, 20, preferably of cast metal, which, as best shown in Fig. 3, is constructed to form a trough, 11, for holding the gum or paste. At the opposite ends of this trough are notches 21 21, Fig. 10, which form bearings for the journals of the guinmi ng-roller 3. The ends of the trough are also formed with notches 22 22, (shown in Figs. 7 and 10,) into which are dropped the opposite ends of the strickle 12. This strickle consists of a bar having a true straight edge, which is adjusted parallel with and very close to the periphery of the gummingroller 3, so that as the latter revolves the strickle will wipe off the excess of gum from its surface and will leave thereon a th'in film of uniform thickness. The thickness of this film may be adjusted by screws 18 13, which pass horizontally through the opposite ends of the strickle and bear agai net the front and rear sides of the rear notches,22 22. By lifting out the strickle and turning these screws forward or back the strickle will be set nearer to or farther from the gummmgroller.

A feed-plate, 10, is placed over the top of thetrough, covering the space in front of the roller 3 and inclosing the strickle. Its ends drop into notches in the ends of the trough, and it has flanges 23 23, Fig. 8, which project inside the trough and prevent its longitudinal displacement. The intake-roller 1 is mounted in bearings over this plate 10, and the guide-bar 9, which is mounted behind the intake-roller, is fixed to the plate. The bearings for the roller 1 are formed by cars 21L 24 projecting forwardly from the bar 9,as shown in Fig. 1. The right-hand one of these cars joins the plate 10, but the left-hand one stands abot e this plate, as shown in Figs. 1, 2, and 9, so that the edge of a sheet of paper may be introduced under the left-hand end of the intake-roller. The latter is reduced in diameter at 25, and a spur, 26, projects upwardly from the plate 10, and enters this reduced portion, thereby forming a partition to separate the left-hand end portion of the intake-roller from the main portion thereof to the right.

The gumming-roller 3 is protected by a hood or cover, 4, which shuts over the trough 11, and has flanges 27 27 projecting atits opposite ends. To the opposite ends of the box 20 are Q ceases pivoted locking-plates 15 and 16, by which the several parts are joined together in suchmanner that they may be readily taken apart forcleaning. Thelocking-plate 16 (shown in Fig. 5) is connected at the right hand end of the box, being pivoted thereto by a stud at 19,- so that it may be thrown back, and when in place it is fastened by a screw, 17, having a milled head,by which it may readily bescrewed in or out. The lockingplate 15,which is shown in Fig. 6, is connected in like manner to the left-hand end of the box. Both plates have recesses 28 28 for engaging the flanges 27 27 on the hood 4, and notches 17 17 for engaging the journals of the gummingroller 3. In addition the plate 16 has a deep notch, 29, for engaging the journal of the intake-roller 1.

The gumming-roller 3 is rotated by a crank, 7, and has a gear-wheel, 5, fixed to its spindle, which meshes with a pinion, 6, fixed to the spindle of the rollerl, so that by the rotation of the crank both the gulnining and the intake rollers are driven. A gravity-pawl, 30, is pivoted to the locking-plate 16', as shown in Fig. 4, and engages the teeth of the wheel 5 in order to prevent the backward rotation of the gumming-roller.

The intake-roller 1 has rubber bands 2 2 placed over it at intervals to give it a frictional surface for engagement with the paper to be fed. These turn freely in notches 8 8- in the bar 9, and the feed-plate 10 directly beneath them is formed with slight depressions into which they project, so that they do not actually touch the'feed-plate; but when a piece of paper or label is inserted between them, as denoted by the arrow a in Fig. 3, they engage or grip it and propel it forward against the gumrned surface of the roller 3. The paper is thrust upward by the latter and enters between it andthe guide-bar 9. This bar has its rear surface adjacent to the gummingroller curved or hollowed out parallel with the cylindrical surface of the roller, as shown in Fig. 3, and stands just sufficiently apart therefrom to avoid being gummed thereby, but close enough thereto to hold the paper into contact therewith during its upward passage, so that the paper receives a coating of gum from the roller. The advancing edge .of the paper as it emerges from the guide-bar 9'is lifted from the'surface of the gumming-roller to which it tends to adhere by means of a spur or finger, 14, which is formed, preferably, on the front edge of the hood 4, as shown in Figs. 1, 2, and 3. The gumming-roller may advantageously be formed with a peripheral groove,into which the point of this finger shall project to insure its taking under the advancing edge of the paper. The gummed paper or label is thus lifted off from the roller 3 and directed upwardly out of the machine in the direction denoted by the arrow 12 in Fig. 3.

When it is desired to gum only the edge of a piece of paper, the latter is inserted under the left-hand end of the intake-roller 1, so that its edge only comes in contact with the gumming-rol-ler 3. In this case the spur 26 prevents its being thrust in too far,so that too wide a coating of gum would be applied to its edge.

I claim as my invention the following defined novel features, substantially as hereinbefore specified, namely:

1. The combination of a trough for holding gum, a gumming-roller mounted to rotate therein, and a stationary guide-bar concaved on itsside adjacent to the roller set close to but out of contact therewith and adapted to hold the paper to be gummed against the surface of said roller. 7 V I i .2.
